Я пытаюсь построить модель отношения продолжения для большого набора данных, который имеет много категориальных переменных, используя пакет glmnetcr.
Я пытаюсь соответствовать этой модели:
fit3=glmnetcr(x=trainElective2[,1:26],y=trainElective2[,27],method="forward")
Это привело меня к следующей ошибке:
Error in y * weights : non-numeric argument to binary operator

Я последовал примеру из RDocumentation: https://www.rdocumentation.org/packages/glmnetcr/versions/1.0.2/topics/glmnet.cr
Кроме того, я не уверен, что использую правильный пакет.
